患者男,28岁。发作性头痛10余年。神经系统检查无阳性体征。头颅MRI示右侧额部内板下见等长T1等长T2混合团块信号影,肿块部分侵入内板内,液体衰减反转回复(FLAIR)序列为等、高信号,DWI为高信号为主,内可见片状等、低信号。MRI示右侧额部颅骨内板下见团块状等、长T2(图1a),等、长T1(图1b)混杂信号影,边界清,FLAIR序列为等、高信号,其内可见小片状低信号影(图1c),DWI(图1d)示主体高信号,内见片状等、低信号。局部颅骨变薄,邻近脑实质受压。病理诊断为表皮样囊肿。详见图1。
Male patient, 28 years old. Attack of headache for more than 10 years. Neurological examination no positive signs. MRI showed the right forehead under the inner plate of the elbow T1 equal length of T2 mixed mass signal, part of the tumor invaded the inner plate, the fluid attenuation reversal response (FLAIR) sequence for the high signal, DWI high signal-based , Visible within the film, low signal. MRI showed the frontal forehead skull see the mass of the plate, etc., long T2 (Figure 1a), etc., long T1 (Figure 1b) mixed signal shadow, clear boundary, FLAIR sequence for such high signal, which can be seen small Flake low signal shadow (Figure 1c), DWI (Figure 1d) shows the main body of high signal, see the film and so on, low signal. Local skull thinning, adjacent to the parenchymal compression. Pathological diagnosis of epidermoid cysts. See Figure 1 for details.
